摘要
从引进的日本土壤改良剂中富集分离得到1株光合细菌,通过形态学观察及生理生化特性鉴定,鉴定为该菌株属于红假单胞菌属。以泰国柳叶蕹菜为试验材料,用GRH-507菌液稀释500倍在蕹菜幼苗期、生长期进行叶面喷施,以等量的清水作对照,在成熟期调查蕹菜的产量。结果表明,喷施500倍GRH-507菌液稀释液能提高蕹菜的产量,两次收割产量分别比对照增产31.03%、20.74%。
One strain of photosynthetic bacteria was enriched and isolated from soil amendment imported from Japan, named as GHR-507. The morphology and physiological-biochemical characteristics of this strain showed it belonged to Rhodopseudomonas palustris. With Ipomoea aquatica as the test material, and the leaves were sprayed by 500 times dilution of GHR-507 at young seedling stage, growth period, foliar application to spray water amount as controls. The plot yields were investigated in ripeness stage. The results showed that the production of first and second batch compared with antitheses increase 31.03%, 20.74%, respectively.
